Abstract
Extended touchscreen pattern. A conductive pattern implemented within a touchscreen (e.g., using indium tin oxide (ITO) such as may be deposited on a substrate composed of polyester or some other material) provides paths for signals traveling through the touchscreen. By monitoring these signal in accordance with some means (e.g., cross point detection, zone detection, etc.) an estimate may be made as to a location of user'"'"'s interaction with the touchscreen (e.g., finger or stylus touching of the touchscreen). The conductive pattern includes a number of conductors aligned in various directions (e.g., row and column conductors) across the touchscreen, and they may be co-planar or separated by a dielectric material. A conductor aligned in one direction includes one or more extended areas that complementarily align with a conductor aligned in another direction. The extended areas of one conductor may be viewed as filling voids (e.g., holes, notches, etc.) of another conductor.
